- The official greens speed measuring tool.
- Official solid extruded aluminium model, perfect to assess greens.
The Stimpmeter is an extruded aluminum bar, with a V-shaped groove extending along its entire length. The tapered end (nearest the ground) has a precisely milled ball-release notch 30″, with a milled out underside, reducing the risk of the rolling ball bouncing when connecting with the green.
The V-shaped groove has an included angle of 145 degrees, thereby supporting a golf ball at two points ½” apart. A ball rolling down the groove has a slight overspin, which is thoroughly consistent and has no deleterious effect on the ensuing measurements.
The ball-release notch is designed so that a ball will always be released and start to roll when the Stimpmeter is raised to an angle of approximately 20 degrees. This feature ensures that the velocity of the ball will always be the same when it reaches the tapered end.
The way putting greens are managed has tremendous influence on their speed consistency.
Most of these factors are known to some degree, but almost all are worthy of research.
Additional Information for Stimpmeter
Knowing the speed of the greens may assist in determining whether a pin setting is fair or unfair. A green so fast (or hole cut in such a position) that a ball cannot be stopped within approximately 2ft (0.6m) of the hole from any point on the green, for example, is probably an unfair challenge.
Championship greens should be fast and uniformly placed, firm but resilient, they should place a premium on well-executed shots, while exacting a penalty for less precise shots. Close daily mowing, a light nutrient program, minimal amounts of water, a good topdressing schedule and a minimum of thatch are the means of achieving greens excellence.
The test for a properly ‘firm but resilient’ surface is the type of ball mark that results from a distance shot onto the green. In turf within the ball mark depression holds together, if it is more a bruise than a scar, the green has the firmness required of a championship green.
The Stimpmeter is robustly built, it is a precision instrument and should be protected from damage. When not in use, it should be stored in a plastic tube or case. Even relatively slight damage to the release notch or to the groove may cause errors.
